Zwiebelduplo

If you have white Duplos in the Kühlschrank, together with some pre-prepared dough for vegetarische Bratlinge with a lot of Zwiebeln in the dough drin, then the white Duplos will somehow pick up the Ausdünstung from the Zwiebeln through the packaging. This results in a funny Zwiebelaroma attached to the white Duplos.
